2016-03-22util: move declarations out of qemu-common.hVeronia Bahaa1-257/+0
Move declarations out of qemu-common.h for functions declared in utils/ files: e.g. include/qemu/path.h for utils/path.c. Move inline functions out of qemu-common.h and into new files (e.g. include/qemu/bcd.h) Signed-off-by: Veronia Bahaa <veroniabahaa@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-03-22Move QEMU_ALIGN_*() from qemu-common.h to qemu/osdep.hMarkus Armbruster1-6/+0
qemu-common.h should only be included by .c files. Its file comment explains why: "No header file should depend on qemu-common.h, as this would easily lead to circular header dependencies." One of the reasons for headers to include it is QEMU_ALIGN_UP() and QEMU_ALIGN_DOWN(). Move them next to ROUND_UP() in qemu/osdep.h, to facilitate removing these ill-advised includes later on.

qemu-common.h should only be included by .c files. Its file comment explains why: "No header file should depend on qemu-common.h, as this would easily lead to circular header dependencies." One of the reasons for headers to include it is HOST_LONG_BITS. Move that to its more natural home qemu/osdep.h, to facilitate removing these ill-advised includes later on. This also lets us use HOST_LONG_BITS in bswap.h instead of duplicating its definition there to avoid cyclic inclusion.

Move them to hw/pci/pci.h and drop the ill-advised include. Include hw/pci/pci.h where the moved stuff is now missing.

2016-03-08cutils: add avx2 instruction optimizationLiang Li1-7/+1
buffer_find_nonzero_offset() is a hot function during live migration. Now it use SSE2 instructions for optimization. For platform supports AVX2 instructions, use AVX2 instructions for optimization can help to improve the performance of buffer_find_nonzero_offset() about 30% comparing to SSE2. Live migration can be faster with this optimization, the test result shows that for an 8GiB RAM idle guest just boots, this patch can help to shorten the total live migration time about 6%. This patch use the ifunc mechanism to select the proper function when running, for platform supports AVX2, execute the AVX2 instructions, else, execute the original instructions.

2015-10-16util - add automated ID generation utilityJeff Cody1-0/+8
Multiple sub-systems in QEMU may find it useful to generate IDs for objects that a user may reference via QMP or HMP. This patch presents a standardized way to do it, so that automatic ID generation follows the same rules. This patch enforces the following rules when generating an ID: 1.) Guarantee no collisions with a user-specified ID 2.) Identify the sub-system the ID belongs to 3.) Guarantee of uniqueness 4.) Spoiling predictability, to avoid creating an assumption of object ordering and parsing (i.e., we don't want users to think they can guess the next ID based on prior behavior). The scheme for this is as follows (no spaces): # subsys D RR Reserved char --| | | | Subsystem String ----| | | Unique number (64-bit) --| | Two-digit random number ---| For example, a generated node-name for the block sub-system may look like this: #block076 The caller of id_generate() is responsible for freeing the generated node name string with g_free().

Since the pow2floor() function is now used in a hot code path, make it inline; for consistency, provide pow2ceil() as an inline function too. Because these functions use ctz64() we have to put the inline versions into host-utils.h, so they have access to ctz64(), and move the inline is_power_of_2() along with them. We then need to include host-utils.h from qemu-common.h so that the files which use these functions via qemu-common.h still have access to them.

2015-07-06Stop including qemu-common.h in memory.hPeter Maydell1-3/+1
Including qemu-common.h from other header files is generally a bad idea, because it means it's very easy to end up with a circular dependency. For instance, if we wanted to include memory.h from qom/cpu.h we'd end up with this loop: memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h Remove the include from memory.h. This requires us to fix up a few other files which were inadvertently getting declarations indirectly through memory.h. The biggest change is splitting the fprintf_function typedef out into its own header so other headers can get at it without having to include qemu-common.h.

There's no need to make special case for this, since all other errors are reported by the child just fine. Let the parent report error and simplify logic in os_daemonize().

2014-10-03util: Emancipate id_wellformed() from QemuOptsMarkus Armbruster1-0/+3
IDs have long spread beyond QemuOpts: not everything with an ID necessarily goes through QemuOpts. Commit 9aebf3b is about such a case: block layer names are meant to be well-formed IDs, but some of them don't go through QemuOpts, and thus weren't checked. The commit fixed that the straightforward way: rename the internal QemuOpts helper id_wellformed() to qemu_opts_id_wellformed() and give it external linkage. Instead of using it directly in block.c, the commit adds wrapper bdrv_is_valid_name(), probably to hide the connection to QemuOpts. Go one logical step further: emancipate IDs from QemuOpts. Rename the function back to id_wellformed(), and put it in another file. While there, clean up its value to bool. Peel off the bdrv_is_valid_name() wrapper.

2014-02-21blkverify: Extract qemu_iovec_clone() and qemu_iovec_compare() from blkverify.Benoît Canet1-0/+2
qemu_iovec_compare() will be used to compare IOs vectors in quorum blkverify mode. The patch extracts these functions in order to factorize the code. Signed-off-by: Benoit Canet <benoit@irqsave.net> Reviewed-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2014-02-20util: Split out exec_dir from os_find_datadirFam Zheng1-1/+1
With this change, main() calls qemu_init_exec_dir and uses argv[0] to init exec_dir. The saved value can be retrieved with qemu_get_exec_dir later. It will be reused by module loading. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
